Presentation Summary: Access to health care services is a fundamental barrier in reducing disparities in disease burden in the US. Physical distance and accessibility to health care facilities can be measured using Geographic Information Systems (GIS) tools, such as those included within the ArcGIS Pro software. This Tech Talk will use sample data on mammography facilities and census tract-level information on women in need of their services in Delaware, to explore how these ArcGIS Pro tools can be used to evaluate access to preventive services. Using the Service Area tool, we will first demonstrate how to visualize and quantify the catchment area of mammography facilities. Second, using the Location-Allocation tool, we will identify locations for new mammography facilities that could improve access for women in locations that are currently lacking. Catchment and location-allocation analyses represent important methodological tools that can be leveraged in service of health equity.
